Description

Technical Field

[0001] The utility model relates to the technical field of air sterilization, in particular to a lamp. Background Art

[0002] There are a large number of microorganisms in the environment where people live. These microorganisms are everywhere and can penetrate any hole. These microorganisms often exist in the form of bacteria or viruses. When people come into contact with these pathogenic microorganisms, it will affect their health. Therefore, conventional lighting fixtures can no longer meet the needs of people's daily lives, especially in some spaces with complex environments, such as livestock farms, farms, workshops, etc.

[0003] As a highly efficient, non-toxic and residue-free physical sterilization method, the new ultraviolet LED light sterilization is widely adopted by people in various fields. In the prior art, some ultraviolet sterilization lamps have been proposed based on complex environments. However, due to the characteristics of ultraviolet rays, long-term exposure can easily have some negative effects on the human body. Therefore, these ultraviolet sterilization lamps cannot meet the problem of human-machine coexistence. Some designs add ultraviolet LEDs to lighting fixtures and combine them with sensors and control programs to start ultraviolet sterilization when no one is around and turn it off when someone is around. Although this method meets the coexistence of humans and machines to a certain extent, ultraviolet rays still cannot work normally when someone is around, and adding sensors also increases costs to a certain extent.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The purpose of the utility model is to provide a lamp to solve the problems existing in the prior art and achieve the purpose of ultraviolet rays coexisting with people during irradiation.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] The utility model provides a lamp, such as Figure 1-2 As shown, it includes a base 2, a sterilization component 4 and a lighting component 5. The sterilization component 4 can emit ultraviolet rays. The sterilization component 4 and the lighting component 5 are both arranged on the base 2. The base 2 is used to be installed on the ceiling. The light emitting end of the sterilization component 4 is facing horizontally and / or obliquely upward and / or vertically upward.

[0034] When there is only one light emitting end of the sterilization component 4, it can be oriented horizontally, obliquely upward, or vertically upward. When there are multiple light emitting ends, any one of them can be oriented horizontally, obliquely upward, or vertically upward.

[0035] When the lamp provided by the utility model is in use, the light emitting end of the sterilization component 4 on the side emits light horizontally and / or obliquely upward and / or vertically upward. When a person or an animal enters the room, the ultraviolet light will not irradiate the body of the person or the animal, or the intensity of the ultraviolet light irradiated on the body of the person or the animal is extremely weak, so there is no need to turn off the sterilization component 4, thereby achieving the purpose of allowing the ultraviolet light to coexist with people during irradiation.

[0036] Under continuous ultraviolet light irradiation, the accumulation of ultraviolet radiation can have a bactericidal effect in the air. When the air circulates continuously, it can form an effective antibacterial effect on the entire space where the lamp is located.

[0037] The lamp provided in this embodiment only needs to meet the requirement that the light emitting end of the sterilization component 4 is oriented horizontally and / or obliquely upward and / or vertically upward to achieve the purpose that ultraviolet rays can coexist with people during irradiation. The installation position and direction of the lighting component 5 only need to be able to achieve indoor lighting.

[0038] Of course, the lighting effect is best when the emitting end of the lighting assembly 5 emits light downwards. Therefore, in the embodiment of the utility model, the emitting end of the lighting assembly 5 is arranged at the bottom of the base 2 and emits light downwards.

[0039] In order to further improve the anti-ultraviolet radiation effect, in the embodiment of the utility model, a shielding plate 8 is provided below the light emitting end of the sterilization component 4 , and the shielding plate 8 is fixedly connected to the base 2 .

[0040] In this embodiment, the shielding plate 8 shields the ultraviolet rays to further improve the radiation protection effect.

[0041] When the light emitting end of the sterilization component 4 is disposed on the side of the base 2 , the shielding plate 8 is also disposed on the side of the base 2 accordingly.

[0042] The embodiment of the utility model further provides another lamp with health care function. The lamp comprises a UVB emitting component 6 , and the UVB emitting component 6 is arranged on a base 2 .

[0043] The UVB emitting component 6 can emit UVB band ultraviolet rays, which can promote the mineral metabolism and the formation of vitamin D in the human body / animal body without harming the human body / animal body, and further promote the absorption of calcium by the human body / animal body.

[0044] In order to improve the irradiation effect, the emitting end of the UVB emitting assembly 6 is also arranged at the bottom of the base 2 and emits light downward.

[0045] In some embodiments, a visible light LED with a wavelength of 405 nm may be further disposed at the bottom of the base 2. When the 405 nm visible light is continuously irradiated for a long time, it may have an antibacterial effect in the air without causing harm to the human body.

[0046] Specifically, the sterilization component 4 is a UVC-LED module; the lighting component 5 is a lighting LED module; and the UVB emission component 6 is a UVB-LED module. The light emitting ends of the sterilization component 4, the lighting component 5 and the UVB emission component 6 are all lamp beads arranged on the lamp board.

[0047] There are many types of lamps in the prior art, such as chandeliers, hanging lamps and ceiling lamps, and the form of the lamp does not affect the installation of the sterilization component 4 in the present application. Therefore, in the embodiment of the present utility model, the lamp can be a chandeliers, hanging lamps and ceiling lamps, such as Figure 8 As shown, when the lamp is a ceiling lamp, a first mounting groove is opened on the peripheral side of the base 2, and the sterilization component 4 is installed in the first mounting groove. The wall surface at the bottom of the first mounting groove can play a shielding role. When the base 2 is a circular structure, the first mounting groove is set as a closed annular structure. When the base 2 is a polygonal structure, a first mounting groove is opened on each side surface to achieve the purpose of light emission from each side surface.

[0048] When the lamp is a chandelier or a hanging lamp, and the distance between the base 2 and the ceiling is large, the sterilization component 4 can also be arranged on the top of the base 2. At this time, the sterilization component 4 can emit light in any direction.

[0049] The base 2 has various shapes. The base 2 in the embodiment of the utility model can adopt any base in the prior art. The only difference is that a structure for mounting the sterilization component 4 on the side needs to be added to the existing base.

[0050] Specifically, the embodiment of the utility model may also adopt a base 2 with the following structure, wherein the base 2 is a long strip structure, the sterilization component 4 is arranged on both sides of the width direction of the base 2, and a shielding plate 8 is arranged on both sides of the width direction of the base 2, and the shielding plate 8 extends from the side of the base 2 along the width direction of the base 2 toward the direction away from the base 2.

[0051] In the embodiment of the utility model, a second mounting groove extending along the length direction is opened at the bottom of the base 2, and a lampshade 1 is covered on the second mounting groove; the lighting assembly 5 is arranged in the second mounting groove, and a clamping groove 10 is arranged on the two side walls in the width direction of the second mounting groove, and the lampshade 1 is provided with a clamping structure corresponding to the clamping groove 10, and the clamping structure is clamped in the clamping groove 10 to fix the lampshade 1.

[0052] like Figure 3-4 and Figure 6 As shown, the bottom surface structure of the second mounting groove is a mounting plate 16, and a fixing hole 15 is provided on the mounting plate 16, and the fixing hole 15 is a threaded hole. The light board of the lighting assembly 5 and the UVB emitting assembly 6 is fixed in the fixing hole 15 by means of a screw 13; a mounting hole 14 is also provided on the mounting plate 16, and a hole column 9 is provided on the back side of the mounting plate 16, and the mounting hole 14 is opposite to the hole column 9, and the stud of the bolt 3 can extend from the mounting hole 14 and extend from the hole column 9 and then screw on the nut, and the base 2 is fixed to the installation location such as the ceiling or the suspension rod by the combination of the bolt 3 and the nut.

[0053] The ratio of the installation height of the sterilization component 4 to the width of the shielding plate 8 is not greater than 1:1.5. For example, in some embodiments, the height of the mounting groove on the side of the base 2 can be set to 15mm, and the width of the corresponding UVC-LED light board is 15mm. Generally speaking, the UVC-LED lamp beads are arranged in the middle of the light board, so the height of the lamp beads is 7.5mm. According to the above requirements, the width of the shielding plate 8 should not be less than 11.25mm. For the sake of safety, the width of the shielding plate 8 in some embodiments is 15cm.

[0054] When the light irradiating downward at a certain angle is blocked, the light at other angles has a larger angle between the irradiation direction and the vertical downward direction. Therefore, when the light emitted by the UVC-LED can reach the height of the human body, the irradiation distance it travels is longer and the attenuation in the air is also greater, so the harm to the human body is smaller and can be ignored.

[0055] According to the national standard "Ultraviolet Sterilizer Hygiene Standard": "Upper flat ultraviolet air sterilizer in the safety area below 2.1m ultraviolet leakage should be less than 5μw / cm2", Fig.10 The relative ultraviolet intensity varies with the distance from the light source. Generally, the installation location of the lighting products is the ceiling or hanging rod, and the height is usually above 2.8m. Figure 6 It can be seen that when it is assumed that the radiation intensity of the light source (each UVC-LED lamp bead in the UVC-LED module) in this embodiment is 72μw / cm2, when it is installed on a ceiling or suspension rod with a height of 2.8m, the light it emits is blocked by the baffle, and the ultraviolet radiation intensity below 2.1m meets the national standard requirements.

[0056] according to Figure 6 As shown in , when the relative UV intensity reaches 5 / 72, the light source distance is close to 1.3 meters. At this time, when the light source at 2.8m shines on the light at 2.1m, its optical path exceeds 1.5m. It can be judged that the ratio of the lamp bead height to the baffle width must be less than

[0057]

[0058] Approximately 1:1.5

[0059] When ultraviolet rays propagate in the air, the attenuation law of their radiation intensity with propagation distance follows the following formula:

[0060] I(l)=Qe -σl

[0061] in:

[0062] I is the ultraviolet radiation intensity at any point i in space, in W / m 2 ,

[0063] Q is the ultraviolet radiation intensity at the ultraviolet light source, in W / m 2 ,

[0064] σ is the attenuation coefficient of ultraviolet light propagating in the air,

[0065] l is the straight-line distance between any point i in space and the light source, in meters.

[0066] In this embodiment, the temperature is kept constant under normal environmental conditions (standard atmospheric pressure, room temperature of 15-30 degrees Celsius, PM2.5 less than 75ug / m 2 , humidity is less than or equal to 50%) is defined as σ=-2.

[0067] So the propagation distance

[0068] When the lamp is installed at a height of h (h>2.1),

[0069] The ratio of the lamp height to the baffle width in this lamp should be less than

[0070]

[0071] In this embodiment, h = 2.8, I = 5 μw / cm 2 , Q=72μw / cm 2

[0072] Therefore, the ratio of the height of the lamp bead to the width of the baffle is 0.7:1.13, which is approximately 1:1.5. In some embodiments, such as Figure 7 As shown, the width of the shielding plate 8 can be shortened. On this basis, in order to ensure the shielding effect, the UVC-LED lamp beads 12 can be arranged as close to the bottom of the UVC-LED lamp board 11 as possible.

[0073] In the embodiment of the utility model, the shielding plate 8 and the base 2 can be integrally formed.

[0074] In the embodiment of the utility model, Figure 5 As shown, the width of the second installation slot gradually narrows from the opening toward the slot 10 , and the bottom edge of the slot 10 is chamfered or rounded to facilitate installation and removal of the lampshade 1 .

[0075] In the embodiment of the utility model, end caps 7 are installed on both sides of the second installation groove in the length direction to prevent foreign objects such as particles and mosquitoes in the external air from entering the interior of the lamp and affecting the lighting effect. The structure of the end cap 7 is as follows: Fig. 9 shown.

[0076] In the embodiment of the utility model, the base 2 and the shielding plate 8 are preferably made of aluminum alloy, which is conducive to heat dissipation.

[0077] In the embodiment of the utility model, heat dissipation fins may be further provided to dissipate heat from the UVC-LED lamp panel. Specifically, the heat dissipation fins may be provided on the shielding plate 8 or on the base 2 .

[0078] The above multiple embodiments provided by the utility model all realize simultaneous lighting and sterilization, and there is no need to turn off the sterilization component when people and animals enter the room, thereby achieving the purpose of coexistence of people and the sterilization process.

[0079] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
